The Official Guide For GMAT® Quantitative Review, 2ND EditionA collection of 36 cards consists of 4 sets of 9 cards each. The 9 cards in each set are numbered 1 through 9. If one card has been removed from the collection, what is the number on that card?

(1) The units digit of the sum of the numbers on the remaining 35 cards is 6.

(2) The sum of the numbers on the remaining 35 cards is 176.

The value of the card can be 1 to 9.

Statement 1) Sum of all the cards of one set = 1+2+..+9 = 9*10/2 = 45

So all the 4 sets = 4*45 = 180

last digit is 6 so card has to have a value of 4 because no other card number will satisfy the condition.

Statement 2) The sum is even more explicit. So definitely we can determine.

Hence option D)
